A research group led by the Al-Azhar University in Egypt has designed a photovoltaic water pumping system (PVWPS) that can be used to supply water for domestic use, irrigation, livestock watering, and village water supply. Used mainly for irrigation, PV-powered water pumps are a viable alternative to diesel-powered water pumps in remote areas. ”The academics also calculated the overall system efficiency by splitting the system output (hydraulic power) by the system input (solar radiation power), or by multiplying the efficiencies of all system components. “The overall efficiency of the system is directly affected by solar radiation, but when solar radiation exceeds 900 W/m2 at noon, this is accompanied by an increase in temperature, which negatively affects the efficiency of the solar panels and thus the overall system efficiency,” they emphasized. “The design of the solar water pumping system goes through several stages, and some information such as daily water consumption, static water level, and the pumping pipes length and diameter must be known,” it specified.
